Reports calls <code>native</code> methods within a <code>synchronized</code> block or method.
<p>
  When possible, it's better to keep calls to <code>native</code> methods out of the synchronized context
  because such calls cause an expensive context switch and may lead to performance issues.
</p>
<p><b>Example:</b></p>
<pre><code>
  native void nativeMethod();

  void example(){
    synchronized (lock){
      nativeMethod();//warning
    }
  }
</code></pre>
